High-Torque (HT) Servo-Worm Reducers
This standard selection of Servo-Worm Reducers are simply perfect for use in applications that demand high performance, precise positioning and repeatability. They were especially developed for work with with state-of-the-art servo engine technology, providing tight integration of the electric motor to the unit. Angular backlash of less than 1 arc-mins is provided standard.
They are available in four sizes (50 mm to 100 mm center length) with input speeds up to 5,000 rpm, reduction ratios from 4.75 to 52:1 and output torque capacities up to 885 lb.ft. A wide selection of motor couplings and mounting flanges are for sale to assembly to nearly all servo motors, and the hollow bore outcome can be utilised to mount productivity shafts, pinion shafts, or other drive elements.
Standard applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials handling axis drives, zero-backlash axis drives and digital line shafting. Industries offered include Material H, ling, Aerospace, Automation, Robotics and Machine Tool.
Gearing: Internal gear style was optimized to supply an angular backlash of less than 1 arc-minutes in assembly, with the choice of “in the discipline” adjustable backlash if necessary.
Bearings: Input angular contact bearings for high source speed, and robust end result tapered-roller bearings for great radial and axial load ability.
Housing: Light weight aluminum housing once and for all heat dissipation, with essential insight flange for servo motors and general mounting on any deal with.
Output: The result bore is available with a compression-type hub or a good ISO 9409-1 flange (see dimension pages). We give a line of equipment to adapt these outputs to right shafting, Rack & Pinions, or other gearing types.
This gearbox utilizes a 30:1 ratio worm-travel reduction for applications that require extremely slow and smooth rotational motion. The worm-drive design not merely minimizes backlash but also eliminates back-generating the gearmotor so a posture can be kept even when power isn’t applied. The precision ground 3/8” stainless steel productivity shaft is supported by dual 3/8” ABEC 5 ball bearings to support lots from any orientation. The ¼” ABS plastic and aluminum structure offers a rigid framework without adding unneeded weight and is very easily installed to any flat work surface by utilizing the base mounting tabs. Our Normal Spur Gear motors will work with this gearbox (engine purchased separately). The Vertical Shaft Worm-Drive Gearbox is simply perfect for turn-tables, time-lapse systems and low-acceleration applications that require high accuracy and torque.
Motor RPM required = 1 / (mins per rotation desired / 30)
Example: 1 / (ten minutes per rotation / 30) = 3 RPM motor had a need to achieve 10 minutes per rotation (at max speed)
now offers an economical right angle gearhead for make use of with small NEMA 23 through 56 and similar compact metric servo and stepper motors. These reducers are most appropriate for basic action and source speeds of 2000 rpm where profile request costs are a major consideration.

Worm Gears are right angle drives providing huge velocity ratios on comparatively short center distances from 1/4” to 11”. When properly installed and lubricated they function as the quietist and smoothest working type of gearing. Due to the high ratios conceivable with worm gearing, maximal speed reduction could be accomplished in fewer space than many other types of gearing. Worm and worm gears are powered by nonintersecting shafts at 90° angles.
EFFICIENCY of worm equipment drives depends to a sizable extent on the helix angle of the worm. Multiple thread worms and gears with bigger helix angle prove 25% to 50% better than one thread worms. The mesh or engagement of worms with worm gears creates a sliding action triggering considerable friction and greater lack of efficiency beyond other types of gearing. The utilization of hardened and floor worm swith bronze worm gears raises efficiency.
LUBRICATION is an essential factor to improve efficiency in worm gearing. Worm gear action generates considerable high temperature, decreasing efficiency. The quantity of electric power transmitted at confirmed temperature raises as the performance of the gearing raises. Proper lubrication enhances productivity by reducing friction and heat.
RATIOS of worm equipment sets are dependant on dividing the amount of teeth in the gear by the amount of threads. Thus one threads yield larger ratios than multiple threads. All EP. worm equipment sets can be found with either left or right hands threads. EP. worm gear sets are offered with Double, Triple, Qua and Single-druple Threads.
SAFETY PROVISION: Worm gearing shouldn’t be used as a locking mechanism to carry large weights where reversing actions could cause harm or injury. In applications where potential damage is non-existent and self-locking is wanted against backward rotation then use of an individual thread worm with a minimal helix angle instantly locks the worm gear drive against backward rotation.
Materials recommended for worms is normally hardened steel and bronze for worm gears. On the other hand, depending on the application form unhardened metal worms operate adequately and considerably more economically with cast iron worm gears at 50% horsepower ratings. In addition to metal and hardenedsteel, worms are available in lightweight aluminum, stainless, nylon and bronze; worm gears can be purchased in steel, hardened metal, stainless, aluminium, nylon and nonmetallic (phenolic).
EP also sells gear tooth measuring gadgets called Equipment GAGES! Gear Gages decrease mistakes, save money and time when identifying and purchasing gears. These pitch templates can be found in nine sets to identify all the typical pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, Exterior Involute Splines, Metric Module “MOD”, Stub Tooth, Great Pitches, Coarse Pitches and Uncommon Pitches. Make reference to the section on GEAR GAGES for catalog quantities when ordering.
